Holographic Operator Interface for Multi-Position Utility Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of working machines, such as self-propelled soil compactors, is hindered by the limited space and increased cost associated with providing multiple control panels and displays that cannot be easily adapted to different operating positions, leading to reduced clarity and operator comfort.
Innovation Solution
Implementing a hologram-based system for operating elements and displays that can be projected virtually, allowing for adaptive positioning and interaction without physical installation, using a projection arrangement and movement/position detection system to generate three-dimensional visual images that can be customized by the operator based on their needs and work status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple control panels and displays are provided for different operating positions, then operator accessibility is improved, but device complexity and cost increase
Solution Approach 1:
A single control panel and display unit is designed to serve multiple operating positions through electronic configurability. The control panel can be electronically configured to provide different layouts and arrangements of operating elements depending on which operating position is detected, allowing one physical unit to replace multiple dedicated control panels.
Solution Approach 2:
The control panel dynamically adapts its configuration based on the detected operating position. The display arrangement and operating element layouts are automatically adjusted in real-time according to the operator's position, transforming a static control interface into a dynamic one that responds to changing operational conditions.
2Adaptability or versatility
If control panels are made adaptable to different positions, then versatility is improved, but device complexity increases
Solution Approach 1:
A detection device continuously monitors the operating position and provides feedback to the control unit. Based on this feedback, the control unit automatically configures the control panel and display arrangement appropriately, enabling the system to adapt to different positions without manual intervention or complex mechanical adjustments.
Solution Approach 2:
The patent replaces mechanical or physical adaptation mechanisms with electronic and software-based solutions. Instead of having physically reconfigurable control panels, the system uses electronic configuration and software control to achieve adaptability, significantly reducing mechanical complexity.
3Adaptability or versatility
If multiple control panels are installed, then coverage of different operating positions is improved, but loss of substance and cost increase
Solution Approach 1:
One control panel and display unit is designed to universally serve all operating positions through electronic configurability. This eliminates the need to manufacture and install multiple separate control panels, reducing material consumption and associated costs while maintaining comprehensive coverage of all operating positions.

AI summary
According to one example, a working machine (10) includes a projection arrangement (36) to generate a hologram (38), wherein the hologram presents a virtual operating element or a virtual display and a movement/position detection arrangement (42) to detect a movement or a position of an operator. The working machine of the example also includes a control unit (44) to control the operation of the working machine based on the detected movement or position of an operator and based on the basis of the hologram generated by the projection arrangement, wherein the projection arrangement is to generate the hologram at different positions or with different content in association with different operating positions to be assumed by an operator (26) on an operator platform (22) or the movement/position detection arrangement is designed to detect the movement or the position of an operator in different operating positions on the operator platform.
